Ophiolites in European Variscides and Uralides: Geodynamic settings and metamorphism

摘要: The most important tectonic and magmatic events in the history of ophiolites Uralides European Variscides occurred almost sinchronously. rocks paleooceanic complexes both regions have similar paleontological isotopic ages. formation Ural Variscan is brought into correlation with a wide range geodynamic settings. mainly correspond to suprasubduction setting, whereas are commonly related rifts mid-ocean spreading centers oceanic crust. main difference origin metamorphic associated ophiolites. high-pressure-low-temperature metamorphism island arc-continent collision, Barrow-type developed at higher temperature under medium-low pressure.
